Nicholas Mc Guire 41c31f6a59 Documentation: devres: note checking needs when converting
There are a number of cases where conversions to devm_* API have been
done but developers forgot that this conversion may imply that return
values need to be checked for failure of internal resource handling
like allocation. While this should be clear, it does seem to be a
relatively common issue with API conversions or maybe "managed" is
being misunderstood ? So add a note to make the scope of "managed" clear.

Sakari Ailus 3d9bfb19bd scripts/kernel-doc: Fix struct and struct field attribute processing
The kernel-doc attempts to clear the struct and struct member attributes
from the API documentation it produces. It falls short of the job in the
following respects:

- extra whitespaces are left where __attribute__((...)) was removed,

- only a single attribute is removed per struct,

- attributes (such as aligned) containing numbers were not removed,

- attributes are only cleared from struct fields, not structs themselves.

This patch addresses these issues by removing the attributes.

The documentation for gen_init_cpio mentions to invoke the tool with

Will Deacon 806654a966 Documentation: Use "while" instead of "whilst"
Whilst making an unrelated change to some Documentation, Linus sayeth:

  | Afaik, even in Britain, "whilst" is unusual and considered more
  | formal, and "while" is the common word.
  |
  | [...]
  |
  | Can we just admit that we work with computers, and we don't need to
  | use þe eald Englisc spelling of words that most of the world never
  | uses?

dictionary.com refers to the word as "Chiefly British", which is
probably an undesirable attribute for technical documentation.

Replace all occurrences under Documentation/ with "while".

In the Function documentation Section of kernel-doc.rst
there is a function_name() function as an example for
how to make a comment about a function.

But at the end of that example there is a reference to foobar

I think that should rather be function_name, because that
was the placeholder the whole example was using.

Christoph Niedermaier 8bed5a5cfc Docs/EDID: Calculate CRC while building the code
The previous version made it necessary to first generate an
EDID data set without correct CRC and then to fix the CRC in
a second step. This patch adds the CRC calculation to the
makefile in such a way that a correct EDID data set is generated
in a single build step. Successfully tested with all existing
and a couple of new data sets.

Christoph Niedermaier d2f112a568 Docs/EDID: Fixed erroneous bits of XOFFSET, XPULSE, YOFFSET and YPULSE
The problem was found when EDID data sets for displays other
than the provided samples were generated. The patch has
no effect on the provided samples that still match the data
used in drivers/gpu/drm/drm_edid_load.c.

The provided samples use small values for XOFFSET, XPULSE,
YOFFSET and YPULSE, where the error doesn't occur. This fix
corrects the use of that values in case of high values, because
the most significant bits were treated incorrectly.

So in edid.S msbs4 should use bit 8 and 9 of XOFFSET and XPULS.
For YOFFSET and YPULSE msbs4 should use bit 4 and 5.

lsbs2 was introduced for a better overview, without
functional change.

Removing also the useless value 63 of all files, because
it is added in the *.S description files and then it is
subtracted in edid.S.
